if santorum wins here tomorrow or comes close to the top, he should have a case to make for why he should be that candidate. but here's the problem. when santorum gets to south carolina in january -- >> it is january. >> the 21st of january, when the votes are cast in south carolina, he's going to find rick perry, newt gingrich, and perhaps michele bachmann. >> still there? >> all down there waiting for him. it's what joe was saying. it's math. >> south carolina will be the super bowl for the true conservative candidates that emerge. and then you're going to have after that in florida and elsewhere, you're going to have romney, you're going to have the anti-romney, and you're going to have ron paul. and romney will have to struggle to get 51% of the votes, because this thing could go on for a while. the other thing i would say is this, looking at newt gingrich, i would not want to be on a debate stage with that man this weekend. >> he's going for the kill now. >> mccain won in a plurality in 2008. he got 30-some percent in south carolina, and that's all he ultimately needed there. so i think the same thing could happen. the next big question in the next three weeks, chris, will conservatives pressure somebody to drop out of the race. will there be pressure on perry, on bachmann, on newt to make room for santorum? >> let me get tough here. suppose this goes to south carolina in a couple of weeks, mitt romney was pro-choice up in massachusetts. he's also lds, which could be a problem with some people, mormon. we don't know that yet.
